COAL-CHU'I'E.

Specification of Letters Patent.

Patented Dec.3 1 918.

Application filed January 25, 1917. Serial No. 144,387.

To a whom. it may concern:

lie it known that I, \VILLIAM V. Hnmz, a citizen of the United States, residing at La Sadie, in the county of La Salle, State of Illinois. have invented certain new and useful Improvements in Coal-Chutes, of which the following is a specification.

My invention relates to chutes used for conducting coal and the like through a window into storage space and particularly to a chute having a door preferably glazed, and adapted to close the end of the chute and a hopper movably mounted .in the chute and autmnatically moved by the door. 1

One of the objects of my invention is to provide a chute mounted in the wall of the building having a metal door or closure pro: vided with a transparent section of glass, mica or the like for the admitting of light to the interior of the building to which the chute is applied.

A further object is to provide a hopper slidahly mounted in the mouth of the chute and connected by suitable means to the door so that when the door is opened the hopper will be drawn out and form an extension to the chute. r

still further object is to provide a protecting plate to prevent the glazed section oi the door from being broken by material delivered through the chute. 1

A further object is to associate with such protecting plate for the glazed section means whereby theplate may he allowed to drop into the lower portion of the hopper when the door is in closed position, thereby olt'ering no hindrance to the passage of light through the glass to the interior of the cellar or basement and whereby the plate is HlItfimtltiCt l ily moved into protecting rela* tion to the glass whentlie chuteis in use. i

' I am aware that coal chutes having a hopper mounted therein and having metal'doors or closures are known. The disadvantages of such known constructions'are that the opening or closing of the door and the m0vemerit of the hopper are independent and thnt surh means is reduiredtdhold the door in opened" position, atso to =li ol'd the hopper in outward position. "lhcse objections are ovorconnhr the (-hutcof my invention.

' In order to enahlathose skilled in the art to more tully understand my invention attienti'nn is directed to the drawings whet-em: I 'iglue l is a vertical .t' 'lltlll thr ugh a horizontal position in the bottom of the hop per when the debris closed'as best seenfinfl V Fig. 1 and tooverlie the glass 18 in the do'or wall of a building showing the construction of the coal chute embodying my invention the same being showirwith the door in closed position. Fig. 2 is a similar view the parts being shown with the door in opened-position.

Fig. 3 is a front elevation showing thedoor in raised position. 1 1'1 I Fig. 4 is a front view bowing the door in closed position. i i

Fig. 5 is a fragmentary viewof the-hopper in outward positionishowing the stops ifor, maintaining the hopper in outward position. Fig. 6 is a view SiII'IlIflP-tO T ig. 1 showing i a modification in the means of unlocking;

tion 13. A frame 14 surroundsth'e opening 11 at the outer end ofthe chute 12 and to it is hinged a door frame 15 by pintles 16 and i 17. In the door 15 is a glass or other-trans parent member 18-. Mounted within and ly+ ing along the inclined: bottom 13 of thechute 12-is a hopper ifiad'apted to be inclosed wholly within the'chute VVhBiI the door is in closed position and ate extend outwardly; therefroln when the door isin openedposltion. This hopper comprises a bottgm mainber 20 and side walls 21am is opematthe top. For moving the hopper 191 employ link arms 22 pivoted at 23 to the hopper and at 24 to the dooiaf On the net edges and onw opposite sides of the doorare perforated lugs 25 to which isfpivoted' av protecting plate 26 adapted to assume a substantially 15 when thedoor is in opened position as best seen in Fig. 2'. To an in thefholding of the plate 26'infront-of the -glassltl attach a chainot other flexible n'reirns to' the protecting plate 26 fastening thefinner I pant to hold "on door in openedpost which the rear tartar imepptrab 'thusis retained in outward 'iibs'ltioh titid 'coh 'tion by providing suitable stopsialnspl the hopper.

These stops serve also as guiding nieans to prevent sidewise play of the hopper as it is moved back and forth by the operation of the door. They also serve as means for guiding the hopper in its rearward travel as it is moved from opened position.

Frame 14 has a flange 29, the opening formed thereby being greater in vertical dimension that the vertical height of the hopper 19 and in length only slightly more than the width of the hopper. Secured to the rearward edges of the side walls 21 of the hopper are angle bar stops 30 which terminate short of the bottom of the hopper as best seen in Fig. 5. When the door is raised and the hopper 19 withdrawn to its outer position these steps 30 will abut the inner faces of the flange 29, thus preventing any further outward movement of the hopper 19. At the outer end of the chute-and positioned so as to clear the side Walls of the hopper are stops 31 as shown in Fig, 5, the height of these stops being such as to contact the stops 30 when the hopper is pulled to its outward position. It will be seen by this arrangement that as thehopper is pul ed outwardly it will ride up over the stops 31 because of the contact therewith of the stops 30 and after clearing the tops thereof fall down in front of them and thus prevent any :lt'urther rearward movement of Also the stops 30 abut the flange 29 on the door frame 14 and thus prevent any outward travel of.the hopper or any tendency to fall outwardly. The links 22 connectin the door and the hop er are so positions that the'door will be lield in opened position as long as the rear edge of the hopper is in eontactwith the stops 31 and the stops 30 abut the. flan e 29.

-FOIlOGkIHg' thedoor 15 w en it is closed I provide a hook latch 32 on the lower portion thereof which engages a catch 33 incorperished in the lower portion of the frame 141as indicated-Vin Fig; 1. When in closed position the parts are disposed as in Fig. 1 with the latch 32. engaging the catch 33 and the latch 32 can not be disengaged except from the inside of the building. When the latch 32 is disengaged the door may be raised thus drawing out the hopper 19. The raising movement of the door'isf continued until the hopper travels over the stops 31 and: the-stops 3O- engage the flange 29 on the inside and the stops 81 On the outside, thus'holdingthe hopper in outward position and the door in opened position. A the door 15 israised to an open position plate 26'will move from the position shown inf Fig. 1 to the position shown in Fig. 2 and overlie the glass 18 in the door 15. If, for

any reason, the plate 26 does not move freely thechain 27 will draw it inwardly thus insuring protection to the glass 18.

In the modification shown in Figs. 6 and tion 35 the purpose of which will be'ex plained later. At the lower end of the plate 26 secured thereto is an offset member 36. Fastened to this member 36 is a flexible member 37 passing through a ring or other device 38 fastened to the upper portion of the chute 12. At the end of the member 37 there is provided a ring or othergmeans larger than the opening in the member 38. This ring is designated by 39. The function of the member 37 of Figs. 13 and 7 is the same as that ofthe member 27 in Figs. 1 and2, that is to draw the protector plate'against the glass in the door when the door ism opened position. The modification shown affords a means for unlatching the door from inside the'building without having to enter the basement where the chute is in position; While the member '37 is shown as.

terminating beyond the member 38, nevertheless, this may be lengthened in any de: sired manner so as to be operated from a distance. As the hinges 1601? the door are so arranged that the pivotal members thereof are outwardly of the point of engagement distance; hence; when it is desired to open the door it is necessary to pull member 37 raising the plate 26 which disengages the latch 34 because of the connection 35 therebetween.

'VVhen is desired td close the door 15 j and move the hopper 19 thedoor '15 is pushed the hop ends of the door being pushed against the wall 10 will be slightly inclined so that when the door l5 i$ lowered or as t e door moves toward Its 010 ed position t e hopper will clear/ the stop; 31 and be pushed backyinto the chute and when-the door is fully closed the/latch 32 will engage the catch 33 thus. sec ring the door in closed position.

I do not limit myself to the exact details d scribed but intendto cover such modificat ons and equivalent thereof is may prop gly come w1thin thescope of my invention.

or 18 my invention to be limited to a strueture containing all of the devices described since obviously all of them are not interdependent although so related as to be used and operated together. For example while prefer to employ the protecting plate for the glazed section of the door it is obvious essential and may be omitted. Also T may 'ainst the'walllO.
